Abstract

Logic coverage criteria are central aspect of programs and specifications in the testing of software. A Boolean expression with n variables in expression 2 n distinct test cases is required for exhaustive testing .This is expensive even when n is modestly large. The possible solution is to select a small subset of all possible test cases which can effectively detect most of the common faults. Test case prioritization is one of the key techniques for making testing cost effective. In present study performance index of test suite is calculated for two Boolean specification testing techniques MUMCUT and Minimal-MUMCUT. Performance index helps to measure the efficiency and determine when testing can be stopped in case of limited resources. This paper evaluates the testability of generated single faults according to the number of test cases used to detect them. Test cases are generated from logic expressions in irredundant normal form (IDNF) derived from specifications or source code. The efficiency of prioritization techniques has been validated by an empirical study done on bench mark expressions using Performance Index (PI) metric.

使用mumcut和最小化mumcut对逻辑覆盖标准进行性能分析
逻辑覆盖标准是软件测试中程序和规范的核心方面。在表达式2n个不同的测试用例中需要一个有n个变量的布尔表达式来进行穷举测试,即使n相当大,这也是很昂贵的。可能的解决方案是选择所有可能的测试用例的一个小子集,它可以有效地检测大多数常见故障。测试用例优先级是使测试成本有效的关键技术之一。本文对两种布尔规格测试技术MUMCUT和Minimal-MUMCUT进行了测试套件性能指标的计算。性能指标有助于衡量效率,并确定在资源有限的情况下何时可以停止测试。本文根据用于检测单个故障的测试用例的数量来评估生成的单个故障的可测试性。测试用例是从源自规范或源代码的非冗余范式(IDNF)的逻辑表达式中生成的。通过对使用性能指数(PI)度量的基准表达式进行的实证研究,验证了优先级技术的效率。
